Regular Database management is a must to keep up to the pace of entries added and queries executed. Database Administrators should find measures to improve the performance of the database and keep all the data in an organized manner. Weekly backup, table structure, updating, deletion of unnecessary files are some of the procedures to maintain the database in a normal state. Sometimes it is observed that while using the delete operation important records get deleted in the SQL server and this causes Database corruption. DBA’s must restore accidentally deleted records as soon as possible. But the question comes ‘How’. Here we will know the steps on how to recover deleted records in SQL server manually and automatically.

The database administrator must be aware of the manual methods of SQL database recovery, so that quick action can be taken without disturbing the normal workflow. In case of recovery of deleted rows from SQL Server, we can use the LSN expanded as Log Sequence Number. LSN helps out for the recovery of accidental delete records in the SQL server if the time when they are deleted is known.

What is LSN (Log Sequence Number)?

Every record that is made in the SQL Server transaction logs is assigned with unique identifiers. It acts as an ID to each record and if it is known then it can be retrieved easily. Hence, It is necessary to have LSN number and Full or Logged Recovery Model before recovery of deleted records in SQL Server 2016, 2014, 2012, 2008 and 2005

Retrieve Accidentally Deleted Records from SQL with LSN

Login to SQL Server and go to database from where records are deleted

In the console type the command SELECT * FROM Table_name. Replace Table_name with the name of the table which had records

Log back database by following query

USE Databasename
BACKUP LOG [Databasename]
TO DISK = N’D:\Databasename\RDDTrLog.trn’
NAME = N’Databasename-Transaction Log Backup’,

Now, check the transaction ID of deleted records and other information from the table by

USE Databasename
Select [Current LSN] LSN], [Transaction ID], Operation, Context, AllocUnitName
fn_dblog(NULL, NULL)

When the transaction ID is obtained get the details and time at which records are deleted

USE Databasename
[Current LSN], Operation, [Transaction ID], [Begin Time], [Transaction Name], [Transaction SID]
fn_dblog(NULL, NULL)
[Transaction ID] = ‘000:000001f3′
[Operation] = ‘LOP_BEGIN_XACT’

Now we have LSN, Transaction ID of records, use RESTORE command to recover deleted records from SQL Server

Recover Deleted D USE Databasename
DISK = ‘D:\Databasename\RDDFull.bak’
MOVE ‘Databasename’ TO ‘D:\RecoverDB\Databasename.mdf’,
MOVE ‘Databasename_log’ TO ‘D:\RecoverDB\Databasename_log.ldf’,

The command will restore all the deleted records back to the table in the SQL server. Verify and check the records are recovered via

USE Databasename_Copy GO Select * from Table_name

This will list the records available in the table and you can check them.
